• The correct address to send your subscribe request to is
  lessons-subscribe@mlm.englishlearner.com
• You must reply to the message asking for confirmation to get subscribed.
• If you don't receive a confirmation message, it's most probably because you either entered an incorrect address (if you subscribed using the subscribe box here) or
• if you were using your e-mail program, you tried to subscribe from a different address - in 99% of the time, this is the reason. Please check which address you would like to subscribe, if you have more than one e-mail address.
• It's also possible that your reply-to address is not correctly set in your e-mail program. Please check if your reply-to address is correct.

If you have problems getting unsubscribed from the list:

• The correct address to send your unsubscribe request to is
  lessons-unsubscribe@mlm.englishlearner.com
• As I said before, 99% of the time you can't unsubscribe because you're trying to send your request from a different address, and not from the one you used when you subscribed. If you have (or had) other addresses, please check them. You can look at the message source (right click on the e-mail, Properties/Details) to find which address the e-mail is sent to.
• Make sure you reply to the message asking for confirmation, or you won't be unsubscribed.
